Enum Arg 

pub enum Arg {
    Value(SqlValue),
    Valuer(Box<dyn SqlValuer>),
    SqlNamed(SqlNamedArg),
    Raw(Raw),
    List {
        args: Vec<Arg>,
        is_tuple: bool,
    },
    Named {
        name: String,
        arg: Box<Arg>,
    },
    Builder(Box<dyn Builder>),
}

Builder/Args 体系使用的动态参数类型。

Variants

Value(SqlValue)

Valuer(Box<dyn SqlValuer>)

SqlNamed(SqlNamedArg)

Raw(Raw)

List

List/Tuple 的统一表示。

Fields

args: Vec<Arg>

is_tuple: bool

Named

Named(name,arg) —— 只在 Build/BuildNamed 的 ${name} 路径上生效。

Fields

name: String

arg: Box<Arg>

Builder(Box<dyn Builder>)

Trait Implementations

impl PartialEq for Arg

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
